Summarise the Design Lessons From a Failed Game Jam Entry

The jam entry did not land the way you hoped, and the feedback is scattered across comments, a few kind words, and one brutally honest playtester. This groups the feedback into themes, finds the one issue that mattered most, and pulls out two lessons genuinely worth carrying into your next jam.
